HAT 800-S

Current Sensors Overview

The LEM HAT 800-S is a single-channel Hall-effect current transducer designed for open-loop current sensing. It measures DC, AC, pulsed, and mixed currents up to 800 A with galvanic isolation between the primary high-power circuit and the secondary low-voltage circuit. The device operates on a supply voltage of ±4 V and provides an analog output signal proportional to the measured current. This board-mount module ensures reliable performance in applications requiring precise electronic measurement of electrical currents.
